Venus and Jupiter, March 02, 2023, 18:37

Equipment:
-Meade 70mm Astrograph Quadruplet APO Refractor
-Sky-Watcher AZ-GTi mount
-Barlow lens NPZ 2x
-ZWO IR-cut filter
-ZWO ASI 183MC camera

Due to the huge difference in the brightness of Venus, Jupiter and its satellites, I had to shoot two separate videos.
Shooting and processing:
1. Shooting a video with normal exposure for Jupiter, but overexposure for Venus (shooting time 18:37).
2. Shooting a video with normal exposure for Venus, but underlight for Jupiter (shooting time 18:38).
3. Addition of frames (separately Jupiter, separately Venus, 250 frames each).
4. Overlay of the unexposed image of Venus from the second video on the overexposed image of Venus from the first video.
5. Adjusting the white balance, increasing the brightness of Jupiter’s satellites relative to the planet’s disk.

The Antlia CaK filter proved to be suitable for capturing the cloud cover of Venus. True, the brightness of the image turned out to be noticeably less than that of a stack of ZWB2 + SZS filters, so I had to increase the camera gain when capturing.
